THILL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 585,660, dated July 6,1897.

Application tiled April l5, 1897 Serial No. 632,317. (No model.) l

T0 all "wh/0111, t may con/cern:

Be it known that we, VICTOR DUMAS, J r., and ADAM KNAPP, J r., citizensof the United States of America, residing at Java, in the county ofNVyoming and State of New York, have invented certain new and usefulImprovements in 'Phill-Couplings; and we do hereby declare the followingto be a full, clear, and exact description of the invention,

'such as will enable others skilled in the art sition and then movingthem forwardly, so-

that they will disengage the bolt carried by the axle-clip, the clipalso carrying a spring which is adapted to bear against a camshapedportion of the thill-iron to hold the parts in close engagement with`each other and prevent rattling, as will be hereinafter fully setforth, and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figurel is a sectional view of a thill-coupling constructed in accordance withour invention. Fig. 2 is a sectional View on the line 2 2 of Fig. l, andFig. 3 is a perspective view of the axle-clip.

A designates the axle-clip, which is adapted to embrace the axle in theusual manner, and this clip is provided with a forwardlyprojectingportion which is bifurcated to provide arms A' A', havingbolt-apertures d. The under side of the projecting portion of the clipis provided with a recess a', and at the inner end of said recess isformed an aperture a2, in which lies one end of a springbar B, saidspring-bar being bent, as shown in Fig. 1, to extend for a shortdistance along the recess ct', from which it projects downwardly andthen upwardly between the members or arms A'. The spring-bar is held inplace by means of the cross-bar a4 of the axle-clip, and formed in theprojecting portion of the clip between the arms A' is a vertical recessas, into which the spring-bar moves, as hereinafter mentioned.

C designates the thill-iron, the rear end of which is flattened andprovided in its upper portion with a serpentine channel O', terminatingnear the center ofthe thill-iron, said channel presenting a curved wallc on one side and a projection c' on the other. The rear end of thethill-iron is cam-shaped, as shown in Fig. l, and is provided with agroove c2, in which the spring-bar B bears, so that when the thills arelowered the cam will exert a pressure upon the spring-bar which willtend to hold the parts in engagement and prevent rattling, and when thethills are raised to a vertical position the cam will be turned torelease the tension upon the spring, and in this position the thills canbe readily moved out of engagement with the bolt of the axle-clip.

' It will be noted that the spring-bar onlyl exerts a tension upon thethill-iron when the thills are lowered, and in this position thespring-bar is moved back into the recess a3 of the axle-clip, being heldin proper position by engaging the groove c2 in the face of the cam.

We are aware that prior to our `invention it has been proposed toprovide a thill-coupling in which the thill-iron is provided with a hatbar or bolt which projects laterally from the thill-iron and engageswith an axleclip having slots, so that the engagement of the parts willbe caused by tirst raising the thills and then moving them to ahorizontal position, and we do not claim such construction as ourinvention; but

What we claim as new,`and desire to secure by Letters Patent, is-

l. The combination with an axle-clip having forwardly-projecting arms A'A', a vertical recess a3 between said arms and a recess a' on its underside terminating in an aperture a2, of a spring-bar B bent at one end toengage the recess a' and aperture a2 and curved at its other end to liebetween the arms A' A', the spring-bar being held in place by thecross-bar of the aXle-clip,substantially as shown and for the purposeset forth.

2. The ccmbinationwith an axle-clip having forwardly-proj ectin gmembers which sup- ICO port a transverse bolt, said Clip being alsoprovided With n vertical recess between l[he arms and on its under sidewith t recess 0, terminating at its rear end in an aperture CL2, of aspring-bar B bent at one end to engage the recess ct and aperture Ca2and curved to lie between the members of the axle-Clip, the spring beingheld in position by the crossbar of the clip together With a thill-ironhaving a flattened rear end forming a cam and provided in its upperportion With at serpentine Channel C presenting a Curved Wall c on oneside l(mnd opposite thereto a projection c', the face of the cam havinga groove c2, substantially as shown and for lthe purpose set forth.

In testimony whereof We aflix our signatures in presence of twoWitnesses.
